MOISTENER.

manera l To all whom. t may concern.' Y Be it known that I, CLYDE R. HANSON, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Meisteners; and I do hereby declare that the following is a full, clear, and eXactdescription This invention relates to the subject of moisteners,l and more particularly to that type of moisteners wherein the material to be moiste'ned is in the form of a continuous strip mounted on `a roll fromv which the material is dispensed as desired.

Thev primary .aim of the invention is to provide simple *means for regulating the amount of the material to be'used, as well as to improve the mechanism that meistens the material.

In' addition to ,the for'egoing,`the invention contemplates improvements in the cutting mechanism for the material,as wellas to provide means whereby when a pre-detern mined amount of the material has been moistened and cut-off, the'tension roll will automatically serve to hold the free endA of the material from a position' where it wouldbe unsightly, orin danger of being frayed or otherwise damaged, yet at all times be 'in a yposition to be readily grasped and pulled y2 is a top plan View.v Fig. 3 is a transverse sectional view taken substantiallyon the line B, Fig. 1. Fig. 4 is a fragmentary view in elevation7 partly broken away, of the con-v trolling mechanism for the material supply.

The improved moistener, in its preferred embodiment 1Ashown in the accompanying drawings, comprises in its general organiza tion a base support that be in the form of a stand, designated generally by the' nu- 'meral 1, the forward end portion being made in theform of a reservoir 2. The side walls` of the reservoir 2 have their upper portions provided with bearings 3 for the reception of a shaft 4 carrying a moistening roller 5, the roller 5 being so disposed that it revolves within the-moistening liquid within the res- Specication of L'ettersjliatent.

ervoir 2, -as clearly shown -inv F ig. 1*'of the drawings. The bearings 3,"as clearly shown in Figs. 1 and 2 of the drawings'fmay' bein the form of slots integral with 'the-walls of the reservoir2 and being enlarged at their upper endsfand contractedfat their lower ends so that the shaft 5.4 Amay be readily dropped therein and normally held therein by the weight ofthe roller VThe front wall of the. reservoir 2 is preferably-cutaway and a'eross such cut-away'portion an outer guide roller 6' extends.

It will be observed from Fig; 1 o'ffth'e drawings -that the disposition off'the roller 6 is .such that the materialA is 'held inV a position so that it will Contact with and slide across the projecting upper surface" ofv the roller when being dispensed.-` Immediately to the rear of roller 5, a guide'roller tends transversely across the: reservoir '2,'the

:rollers 6 and 7 beingpreferably disposed' in the vsame horizontal plane.,V Iol'ler 7v is wallof the reservoir 2 and preferably such' bearing 8 is inthe form of a slot havinga forwardly extending 'portion that forms the journal for said' roller 7 and a vrearwardly projecting portion that forms a` journal for the shaft 9 ofv a tension roller 10. 'A pair of standards 11 are carriedv by the sides of the reservoir 2, said standards being connected at their upper ends by the horizontal bar 11a that forms a rest for the knife 12, theknife being secured to', and projecting forwardly from, the rest in any convenient'manner. The standards 11 are preferably detachably connected to the sides of the reservoir in such ,mounted in a bearing` 8 formedin the side i a mannerthat they maybe quickly dismantled, a convenient method of so attach-A ing them being by utilizing nuts and bolts. The shaft of'rol'ler 10 is preferably releasably held to its journals by means of the latch hooks 13 that engage the projecting ends of the' said shaft, as shown in'F ig. 2 ofthe drawings.

Adjacent its rear portion, a standard is carri'edby one side oi the stand 1, said standard having the shaft 15 of the material roll mounted, thereon. -Theshaft 15 carries the stationary' and the removablefguard plates; 15a and 15b, respectively, the plate 15b being held to the shaft by the resilient "arms 16 and adjusting nut 1.7 mounted on said shaft 15. Lugs 15c project from the stand and carry the bar 15d that extends through an opening in the stationary plate and through a slot in the removable plate, and serves as a support for said plates, in a manner well understood.

Forward of the standard 1l the stand 1 is equipped with upstanding bearings 1S which may be of the slotted type, for the shaft 19, and centrally said shaft carries a 'pulley 20 that is so disposed that it lies above and at the forward end of a clearance slot 2l that extends longitudinally of the top of the stand 1. The inner surface of the rear wall .of the stand 1 is provided with an eye -,towhich one end of a spring 23 is attached, the other end of said spring being attached to a cable 2l that passes through the slot 21 and is partly wound around and fastened to the pulley 2U. The arrangeinent of the pulley and spring is such that said spring opposes forward rotary movement of the pulley. Shaft 19 projects beyond one side of the stand 1 and has a master gear 25 mountedthereon, the master gear 25 being in mesh with a pinion 27 mounted on a projecting end of shaft 19. The gearsZ and 2T are inclosed in a housing 2G carried byl and offset from one side of stand 1, sa-id housing having a central hub, 28 that engages shaft 19, Housing 26 isv flat and circular to give the same a dial appearance, and at its upper edge portion is-.provided with regularly spaced opening 9.9 adapted to be selectively engaged by the stop 31 that governs the supply of material dispensed.

The stop 30 serves to restrict the rearward4 movement of shaft 19. An indicator 32 is fast on shaft 19 and by contact with stops ,30 and 31 limits the forward and rearward movements, respectively of said shaft.

rlhe invention is primarily intended for use in connection with gummed paper strips, and itis preferred to use a moistening roller therefor that is not porous. It is preferred that the roller 5 be of metal, and such roller does not apply the moistening fluid evenly and smoothly, but in this invention the guide roller G is so disposed relatively to the roller 5 that it also acts as a spreader for the moistening fluid, as will be clear.

'n operation, the stop 31 is selectively engaged with one of the openings 29 in accordance with the length of the strip of tape that is to be permitted to be severed from the roll, and theystripI then grasped forwardly of roll 6 and pulled outwardly, when the limit of the supply has beenreached by contact of the indicator with stop 31, the tape strip is brought into contact with knife l2 and severed thereby. The outwardpull on the material distentls spring 23 and after they material has been severed the tension'of said' spring, through thevcablc 2l, shaft 15), pulley 20, ears and 27 release the tension on roller l0.i In other words, the relation of rolle; i0 with the spring and gears and asmenare sociated parts is such' that an outward pull on the r4material is opposed and finally stopped when the indicator contacts with stop 3l, and when such pulling movementhas ceased, the roller 10 is subjected to a retrograde movement by reason of the tension imparted to the spring by such pulling move ment, which retrograde movement retracts the material and holds it inplace to be readily grasped.
